COMBINED DOOR KNOB: AND LOCK.

Application filed October 29, 1924. Serial No. 746,485.

To all whom it may concern:

Be it known thatI, JosnPH SONNENBERG, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Combined Door Knobs and Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make. and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in combination door-knobs and locks; and, the present invention has reference, more particularly to a novel door-knob, the spindle of which is of tubular construction provided with the knob attached thereto, with a key-operated mechanism for actuating a bolt, by means of which the door is ordinarily maintained in its closed position within the door-frame.

The present invention, therefore, has for its principal object to provide a novel and simply-constructed, as well as an effectively operating combination door-knob and lock, of the general character hereinafterimore fully set forth, with a view of producing greater neatness in door-construction, owing to the fact that the usual door-locks and their escutcheon plates may be dispensed with.

Other objects of the present invention not at this time more particularly enumerated will be more fully set forth in the following specification.

With the various objects of the present in vention in view, the said invention consists, primarily, in the novel combination doorknob and lock hereinafter set forth; and, the said invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, all of which will ,be'morefully described in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of the said specification. 1

The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a doorknob made according to and embodying the principles of the invention, showing inaddition, in said view, fragmentary portionsof a door and the door-frame;;Figure2 isa horizontal section ofthe same, saidsection 'being taken on line 22 in said 'Figure -1;

and Figure. 3 is a vertical section,taken on line 33 in said Figure 1, the door-knobs and spindle of the device, however, being represented in elevation. I

Figure 4: is a vertical sectional representation, taken on line 44 in Figure 3; Figure 5 is a horizontal sectional representation, taken on line 55 in Figure 2; and Figurefi is a horizontal sectional representation, similar to Figure 2, the spindle andbolt-containing shell, however, being shown in elevatio'n.

Figure 7 is a View similarto Fi-gurefl,

except that the various parts'of the lockmechanism are shown in elevation, with the bolt represented in its unlocked relation with the key-operated mechanism of the device; and Figure 8 is a view-similartoFigure 7, illustrating the various parts in their locked relation. i 1 a Figure 9 is a perspective view of the bolt employed with the device; and Figure 10 is a collective view, showing in elevation, portions of the spindle of the device.

Similar characters of reference are employed in all of the said above described views, to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicates a fragmentary portion of a door, and 2 a similar portion of the door-frame. Asindicated imthe several figures of the drawings, the door is provided with a socketed portion, as 3, usually of cylindrical crosssection, and with the laterally extending tubular portions 4: and 5, which communicate with said portion 3, substantially as shown. Suitably secured upon opposite sides of the door, by means of screws 6, or in any other suitable manner, are the usual rosettes? and 8, respectively provided with the centralopenings 9 and 10 fitted in alinement with therespective tubular portions etand 5,. Asshown, the said rosettes 7 and 8 are also respectively provided with recessed portions lland 12, into which are suitably fitted the shank-portions of suitably shaped door-knobs,,as 13 and M, substantially as shown in Figures 2, 3fand 6 of the drawings. These knobs arealso of tubular Structure, one tubular portion 15;, of

I and 14-, and for operatively securing the said door-knobs, by means of set-screws .18, or

settes 7 and 8, for mounting upon thepro jecting end-portions of said member 17, the tubular shank-portions of the door-knobs 13 other suitable means, upon the respective end-portnons'of said member 17. In its opposite sides, and centrally disposed between the end-portions of the said member 17, the

latter is formed with suitable openings or slots, as 19 and 20, and suitably fixed within said member 17, at desired locations, are stops or retaining discs 21 and 22,- provided with openings or perforations 23 and 24. Movably disposed within the said tubular member 17, between the said stops or retainingd-iscs21 and 22 is a lock-spindle receiving tubular element 25, the tubular. portion or bore 26 of which is of a squaredor similarlyshaped cross-section. In its opposite sidesthe said element 25 is made with elongated openings 27 and 28, disposed in angular or helical relation across each other, substantially as representedin Figure 8 of the drawings. Concentric with the said member 17 is a tubular bolt-actuating member 29, with oppositely extending bolt-actuating wings or fingers 30 and 31, and with perforations 32 and 33 in its opposite sides.

A pin 34 is employedin a manner as shown in Figures 2, 5 and 7 for maintain ingthe said members or elements 17, 25 and 29' in their assembled and operative relation. I

Suitably secured within the tubular portion- 15' of each door-knobis a cylindrical shell or casing 35,,theouter en-d portion of each shell or casing being flush with the end-surface of the knob. Rotatably disposed within each shellor casing 35, and

. suitably maintained therein against displace ment is a key-receiving barrel 36, provided in its inner end-portion with a disc 37, or

' similar means, which is provided with openings or perforations, as 38, for the reception of the actuating lugs or teats 40 of a key 39, for actuating the said barrel in each door-knob, as will be understood from an inspect-ion of Figure 2 of the drawings. Qonnectedwith and extending from. each .disc 37 is a lock-spindle 41, the spindles corresponding in cross-section to the crossseetion of the tubular port on or bore 26- of the inner tubular. element 25, for operatively V v fitting the free end-portions of the respectivelock-sp indles 41 into the said tubular portion: or bore 26,. as indicated in said Figure 2 of the drawings. In order that arranged under compression between the disc 22 and the inner end of the key-barrel containing shell or casing 35 of the doorknob 13, as shown.

Referring now more particularly to Figures 7 and 8 of the drawings, it will be seen that the door 1 which is provided with a lateralbore 3 has snugly-fitted and suitably secured therein a bolt-receiving shell or ca'sing,as 42. Movably disposed within this shell or cas ng is a bolt-member 43, having a chamfered or other suitably formed latchplate engaging end 44, adapted toenter" a suitably formed latch-plate 45, or other suitable bolt-receiving means, with which the door-frame 2 is provided. Extending rearw ardly from said bolt-member 43 is a plate 46, said plate at its inner end being forked or bifurcated, as at 47 Connectedwith the said members 47, are U-shaped receivlng elements, as 48, for receiving therein the previously mentioned bolt-actuating wings or fingers 30 and 31, as shown in said Figure 8 of the drawings.

Also connected with the said elements 48.

are rearwardly extending rods or pins 49, and forwardly projecting stopmeinbers 50, and connected with the free ends of the said rods or pins 49 is a guiding disc 51. The

inner end of the said bolt-receiving shell or casing 3 is marginally flanged, as at 52, and is provided with another disc 53. Acornpression spring 54 is placed between the said discs 51 and 53, asshow'n. In its opvided with suitable openings 55 and 56, the

said. openings being in alineinentwith the previously mentioned openings 4 and 5 in the door, as shown in the several figures of the drawings.

When the various devices and parts of the herein-above described lock-mechanism are in their assembled relations shown in Figures 2, 6 and 7 of the drawings, with the wings or fingers 30 and 31 withdrawn the disc 51 being caused to assume the posi- I tion shown insaid Figure 5, and withthe coils of the spring 54 more fully compressed between said disc 51 and the disc 53] As soon as the knob is releasechthe spring 54 again returns the bolt and the'actuati-ng .posite sides, the said shell or casing 3 isproelements to their normalinitial positions, as will be evident. Thus, the door may be readily opened and closed. To enable proper action of the wings or fingers, when turning, the said shell or casing 3 is also provided in its sides with other openings, as 57, the purposes of which will be selfevident, more particularly from an, inspection of said Figure 5.

In order to lock the bolt-member 4L3 against movement, by inserting a key 39 into either door-knob, the lock-spindle can be properly turned, and actingasa key for the tubular member 25, will also turn the latter, with the pin 34 riding in the angularly disposed slots 27 and 28. Consequently the pin moves also in the longitudinally extending slots 19 and 20 of the tubular member 17, whereby a sliding movement of the tubular member 29 and its Wings or fingers 30 and 31, longitudinally upon the member 17, will also be produced. This movement of the member 29 causes the wings or fingers 30 and 31 to ride directly into the U-shaped receiving elements 48, into locked engagement therewith, ,so that the knobs can not be manipulated, and whereby the bo1t-member will be maintained in its locked engagement with he latchplate 45, as will be evident. Consequently the closed door is also locked against open- I rom the foregoing description of the present invention, it will be fully understood, that I have produced a neat arrangement of locking mechanism for doors, combined directly with the door-knobs thereof,

the mechanism being readily actuated by the insertion and turning of the key in either knob.

I am fully aware that changes may be made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the various de vices and parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings. 7
